The Lowdown
Alright, Rusty here again. Let’s cut through it – Kennebunk Beach is a tough ticket for the next week and a half. From now until around September 20th, it’s basically flat or junky. The energy numbers are all under 100 (50, 45, 22… weak stuff), and the swell is tiny. Not worth the drive.
First sign of life is Sunday the 20th afternoon. A 3ft swell from the SSE with dead calm wind – glassy. Energy hits 124 (moderate wave energy), but the waves are still very ordinary. It’s a start, but nothing special.
Monday the 21st morning brings 4ft from the NE with a clean cross-off breeze. Energy at 169 (moderate), but still just ordinary surf. The rest of that week stays poor.
Now, here’s the payoff. Thursday the 24th of September is the one. The afternoon shows 8ft from the ESE with a 9-second period, solid offshore wind from the NE at 16 mph, and energy cranked to 1141 (strong wave energy). That’s big, expert-only territory. Clean, powerful, and mean.
Friday the 25th keeps it going – 8ft in the morning and 8ft in the afternoon, both from the ESE with an 11-second period (proper groundswell) and fresh offshore winds (19 mph in the morning). Energy is massive at 1356 and 1311 (very strong wave energy). This is for the experienced crew only; the long period will make it pitchy and heavy on a beach break.
Saturday the 26th morning drops to 6ft from the ESE, still with that 11-second period and light offshore wind, energy at 815 (strong). Good for strong intermediates, but the afternoon turns onshore and messy.
After that, the swell fades into the end of the month with tiny waves and poor wind. So, don’t waste your time until the 24th – then it’s game on for the big dogs.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Kennebunk Beach is 17 km (11 miles) from Biddeford. If you plan a vacation in Maine, look for hotels and other accommodation in Biddeford. Biddeford has rooms for a wide range of budgets as well as car hire and transport links.
